SPECTACLE-PLIERS.

Specification cf Letters Patent.

Patented Mar. 12, H8.

Application filed October 15, 1917. Serial No. 196,730.

To all whom it may concern Be 1t known that I, ELzIn C. CHAMBERLIN,

a citizen of the United States, residing at vide novel and improvedpliers for that purpose, in order that the straps between which thelenses are secured, can be elongated to accommodate the apertures of thelenses when `they areV located farther from the edges of the lenses thanthat for which the mounting is made.

It isv also the object of the invention to provide a tool whereby thestraps can be lengthened so that their apertures correctly register withthe holes drilled in the lenses, and whereby the job will be neat andstrong,

`lwithout weakening either the mounting or lenses.

When the rivets, screws or other securing elements are engaged throughthe lenses and straps, with said straps shorter than they should be, dueto the location of the holes of the lenses farther from the edges thanthat for which the straps were intended, this will serve to create abreaking pressure on the lenses between said holes and the edges of thelenses adjacent to the mounting, which not infrequently causes thelenses to break off. lVith the present pliers the strap can be elongatedto properly receive the securing elements, and avoid such breakingpressure.

1t is also the object of the invention to provide spectacle pliers forthe purposes indicated, which will be extremely simple and inexpensivein construction, as well as being thoroughly practical and efficient inuse.

'With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention can be made within the scope of the handleswhat is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure l is a side elevation of the pliers.

Fig. 2 is another elevation thereof, looking at right angles to the lineof view in Fig. l,

being partially broken away.

Fig. 3 is an enlarged elevation of the jaws as in use.

Fig. 4 is an end view of the jaws.

Fig. 5 is an enlarged sectional detail showing the die of one jaw forelongatingthe strap.

The pliers comprises the 4crossed and pivoted levers l and 2 adapted tobe Vswung toward one another b v the hand, and provided at one end withthe jaws 3 and 4, respectively. The jaw 3 is slightly shorter than thejaw 4 and the face thereof confronting the jaw 4 is flat, as at 5, andprovides an anvil. The end of the jaw 3 is preferably rounded and thin.

The jaw 4 is provided at the end thereof with a transverse rib 7projecting toward the plane of the anvil face 5 and end 6 of the 3. Therib 7 is rounded transversely, and the end of the jaw 3 terminatesbetween the opposite sides of the rib 7. That portion of the jaw 4 inrear of the rib 7 is spaced from the jaw 3. and the rib 7 provides a diefor lengthening or elongating the strap of the spectacle mounting. Saidrib or die 7 is provided intermediate its ends with a notch 8transversely of said rib and longitudinally of the jaw 4, and said notchis concaved longitudinally of the rib or transversely of the jaw, asseen in Fig. 4, and eonvexed transversely of the rib or longitudinallyof the jaw, as seen in This enables the rib or die to properly andelfectively lit the strap. The end of the jaw or anvil 3 overlaps therib and extends across the notch 8.

In Fig. 3, there is illustrated an ordinary rimless spectacle mountingincluding the bridge 9 and the pairs of straps l0 atthe ends thereofhaving apertures for the anchoring of the lenses between said straps asusual. The straps 10 are malleable, so that they can be bent or Workedto conform to Fig. 5.

. i die Twillmashthe'strap 10 down the dethe lenses. In using thepresent implement, the thin end of the jaw anvil 3 is inserted betweenthe straps, as seenA in Fig. 3, withY the strap; to be elongated restingflatly on the anvil surface and projecting rearwardly thereon. rhemounting is so arranged that the notch 8 of the rib or 'die 7 will fitsnuglyY transverse widening; due tortheiafact that the strap fits withinthe notch. 8, so that"the-rib straddles thestrap, While thel curvatureof the notch 8', as seeny in Fig. 5, will cause-the pressure applied'yto the strap to `elongate f said?` strap. `The amount of elongation isdetermined byv the amount of'pressure'applied, 'andv the strapl'can beshiftedl 'longi-` t-udinallyY slightly oIr the or Vanvil 3,

when further elongation 1s required. fThe;y

indentation formed: on the strap bythe rib orf' die willi hardly bediscernible, and will 'f be;VA curvedl in harmony7 with the formation-of the strap. Each of the straps 10.1 ofthe,

` r''Yimounti-ng can, therefore, be lelon gated the desired amount, sothat the apertures thereof will register lorfeoinci'de with; the holesin.

The device can not only be used for elonviding an anvil7 the otherhaving a rib projecting toward the anvil to mash an article thereon forelongating it, said rib havin a notch to, tit the article, and the notchbeing concaved longitudinally of the" rib and conveXed transverselythereof.
